Fifth Grade (5): Geometry & Measurement (GM)

Describe, identify, classify, and construct triangles (equilateral, right, scalene, isosceles) by their attributes using various mathematical models.
Describe, identify, and classify three-dimensional figures (cubes, rectangular prisms, and pyramids) and their attributes (number of edges, faces, vertices, shapes of faces), given various mathematical models.
(Content unavailable)
Recognize and draw a net for a three-dimensional figure (cube, rectangular prism, pyramid).
(Content unavailable)
Determine the volume of rectangular prisms by the number of unit cubes (n) used to construct the shape and by the product of the dimensions of the prism 𝑎 ⋅ 𝑏 ⋅ 𝑐 = 𝑛. Understand rectangular prisms of different dimensions (p, q, and r) can have the same volume if 𝑎 ⋅ 𝑏 ⋅ 𝑐 = 𝑝 ⋅ 𝑞 ⋅ 𝑟 = 𝑛.
Estimate the perimeter of polygons and create arguments for reasonable perimeter values of shapes that may include curves.
(Content unavailable)
Measure and compare angles according to size using various tools.
(Content unavailable)
Measure the length of an object to the nearest whole centimeter or up to 1/16 inch using an appropriate instrument.
(Content unavailable)
Apply the relationship between millimeters, centimeters, and meters to measure, convert, and compare objects to solve problems.
Estimate lengths and geometric measurements to the nearest whole unit, using benchmarks in customary and metric measurement systems.
